Title: Leak fuel gas discharging structure of automobile
Inventor: ONO TOHRU
IPC: F02M21/02
Filed: 2002-02-19
Abstract: A leak fuel gas discharging structure for an automobile includes a hollow reinforcement member extending between a floor panel and a wheel house and interconnecting an underfloor space and an internal space of the wheel house. The wheel house has a portion facing a filler recess and having an opening which through which the filler recess and the internal space of the wheel house are connected together. The filler recess is normally closed by a filler lid with a clearance defined between a peripheral edge of the filler lid and a peripheral edge of the filler recess.      By the structure thus arranged, a fuel gas, leaking from a fuel tank disposed in the underfloor space, is discharged outside the vehicle body.

Patent CA-2373858-A1 (CA)
Inventor: GAVIN EDWARD J
IPC: H01J49/40
Filed: 2000-05-12
Abstract: A method and system of detecting mass to charge ratio of ions. The method includes producing charged ions in a vacuum, accelerating the charged ions i n an electric field into a free flight tube and detecting the charged ions at a detector associated with the free flight tube. A control system selects a bandwidth for filtering a signal produced by the detector and the signal produced by the detector is then filtered with a variable width digital filt er based upon the selected bandwidth. The bandwidth for filtering the signal ma y be selected from a look-up table within the control system based upon the ma ss to charge ratio of an ion of interest. Alternatively, a peak bandwidth withi n the signal produced by the detector may be determined and the signal produce d by the detector may then be filtered with the variable width digital filter based upon the determined peak bandwidth.
Patent CA-2374993-A1 (CA)
Inventor: CURTIS GRAHAM EDWARD
IPC: B61C15/10
Filed: 2000-05-08
Abstract: If the wheel/rail adhesion for a railway vehicle is insufficient, then the wheels may slip when braking. If slipping is detected, a control sys-tem (22) may reduce the brake pressure to permit a controlled level of slip and so to optimise the brak-ing force for the available adhesion. By determining the pressure supplied to the brake cylinder (18), a sig-nal (30) may be obtained which indicates the value of the adhesion. Alternatively the adhesion may be monitored by detecting any discrepancy between the braking deceleration demanded by the driver and the observed deceleration. The adhesion signal may acti-vate a warning. It may also be used (32, 34) to adjust the rate at which sand is supplied by a sander (35) to the wheel/rail interface. The rate at which sand is sup-plied may also be adjusted in accordance with other parameters such as the train speed.

Title: Round bale trailer and conveyor chain therefore
Inventor: DELAURIER RONALD T
IPC: B60P1/36
Filed: 2002-03-14
Abstract: A trailer for transporting cylindrical bales comprises a pair of rails and a conveyor chain located between and below the rails such that a bale is maintained in position on the conveyor chain by the rails. The load engaging face of the conveyor chain comprises a plurality of resilient pads having a roughened surface to increase friction between the pads and the bale without protruding into the bale. The load engaging face can slide with respect to the bale. First and second loading arms are operative to raise first and second bales onto corresponding conveyors. A third loading arm raises the first bale from the first conveyor to allow the first loading arm to raise a third bale from the ground and position it on the first conveyor, and then lowers the first bale to rest on the second and third bales.

Title: Frequency translator using a non-periodic local oscillator signal
Inventor: MANKU TAJINDER
IPC: H03D7/16
Filed: 2000-09-01
Abstract: This patent describes a method of removing the LO-leakage and 1/f noise problems associated with direct conversion RF receivers and other demodulators. In order to solve this problem a virtual LO.TM. signal is generated within the RF signal path which is tuned to the incoming RF signal. The virtual local oscillator (VLO) signal is constructed using signals that do not contain a significant amount of power (or no power at all) at the LO frequency. Any errors in generating the virtual LO signal are minimized using a closed loop correction scheme.

Title: Apparatus and method for purification of water
Inventor: SAWADA YOSHIYUKI
IPC: C02F1/52
Filed: 2001-09-21
Abstract: A method for the clarification of water using an apparatus which is equipped with, in the order from the polluted water feed side, an electrolysis vessel (1) for electrolyzing a polluted water, a gas mixing tank (2) for admixing the electrolyzed polluted water with carbon dioxide, a coagulation vessel (3) for coagulating the impurities in the polluted water by admixing the water with Fe3+ supplied from a coagulant preparation device (7), and a floatation separation tank (4) for floating the coagulated impurities and separating them. In the method, the electrolysis of a polluted water by means of the electrolysis vessel (1) lowers the zeta potential of colloid particles in the polluted water and the resultant polluted water is admixed with Fe3+ in the coagulation vessel (3), which leads to the reduction of the amount of positively charged Fe3+ to be added for neutralizing the colloid particles.  Accordingly, the method and the apparatus can be used for removing impurities in a polluted water with a reduced amount of a coagulant and with good efficiency.

Abstract: An object beam divided by a light division means 12 is caused to enter an optical fiber 23 and the object beam emitted from the optical fiber 23 is then caused to enter a photo-refractive polymer layer 6. On the other hand, a reference beam divided by the light division means 12 is irradiated on the photo-refractive polymer layer 6 from the opposite side. In this manner, the object beam is superimposed on the reference beam in the photo-refractive polymer layer 6 to form an interference pattern or fringe corresponding to the strength of the light intensity. The interference pattern is recorded on the photo-refractive polymer layer 6 as a diffraction grating 4. This diffraction grating 4 exhibits a specific characteristic to emit the object beam emitted from the optical fiber 23 in the direction of the reference beam, namely parallel to an optical axis of the optical fiber 23.
